Dear all,

I am still getting used to my 2018 MacBook Pro 15 inch and macOS (10.14.3). Thus, I would like to know whether or not it is normal, that at the start of scrolling a page the page jumps a little.

Here is how I noticed it:
1. Opening a pdf document with a double click.
2. Waiting a few seconds until the Touch Bar dims.
3. Sliding two fingers vertically over the trackpad.

After the single jump the page moves smoothly. I only noticed the jump if the Touch Bar is dimmed. If the trackpad is released and then again two fingers are moved over the trackpad before it dims there is no jump.

Can you confirm the behavior?

Thanks and best regards,
Fabian

I had the same problem with my 2017 15" MacBook Pro. I found that turning off 'Turn keyboard backlight off after X of inactivity' in System Preferences > Keyboard, fixed this issue

Dear ncrypt,
This is the solution. Thank you. I would have never suspected this to be the problem. How did you find the solution?

I think I saw that as the solution in another thread when I was experiencing the same issue :)
